A reservoir-based storage and delivery system has a reservoir body equipped with a top assembly, a bottom assembly and a piston assembly. The contents of the reservoir are allowed to expand and contract during the thermal cycle due to the ability of the piston assembly to float within the reservoir, which eliminates the need for dead head space.

This invention discloses an auxiliary fixing device for unloading oil pipe of metal oil storage tank, including a ground which is provided with a collecting chamber for storing fuel oil, the collecting chamber is provided with an oil port with an opening upward, the external space is provided with a conveyor structure for conveying fuel oil to the collecting chamber. When the device is working, it can fix the oil delivery hose with good fixation, so as to facilitate the stability of the fuel delivery and prevent the fuel leakage. If the fuel delivery vehicle moves automatically in the process of fuel delivery, it pulls the fuel delivery soft. The device can automatically cut off the fuel delivery in the fuel delivery hose, and release the fixation of the fuel delivery hose, so as to directly pull out the fuel delivery hose and prevent a large amount of fuel leakage.

A fueling adapter configured to permit a fuel dispenser which terminates in a twist lock mating assembly to be used to supply fuel to a fuel tank which has a fuel receiver outfitted with a dry break connector connected thereto, said fueling adapter comprising a dry break assembly rotatably connected to a twist lock assembly via a rotational connector.

System and method for providing a warning to a driver when a tanker truck is in a potential hose drive-off situation. The system and method are designed to detect when a hose or other conduit is in close proximity or attached to the tanker truck and alert the driver. This hose drive-off warning system and method may also physically prevent the vehicle from driving away in some embodiments while the hose or other conduit is still attached to the vehicle.

An emergency detachable pipe coupling configured to decouple a female coupling member and a male coupling member which are coupled together when an external force makes the male coupling member tilted at a predetermined angle relative to a female coupling member. When the male coupling member is tilted, a pressing surface of the male coupling member presses a to-be-pressed surface of a locking element restraining member of the female coupling member to displace the locking element restraining member to a release position where a locking element becomes displaceable to an unlocking position.

The present invention relates to a pneumatically, high pressure gas powered emergency release coupling control and monitoring system (S) comprising a powered emergency released coupling (1) arranged in a fluid-supply line (32) for conveying hazardous fluids, said powered emergency released coupling (1) comprising a couple of coupling members (10, 11) provided with mating faces (10A, 11A) for sealing engagement of the coupling members (10, 11) and formation of a pressurizable chamber (12) between said coupling members (10, 11), said system (S) comprising an actuation line (7) connected at its one end to the pressurizable chamber (12) and at its other end to a source (C) of high pressure gaseous media (G.sub.H), preferably high pressure nitrogen gas, an first actuating device (4A, 4B) arranged in the actuation line (7), wherein said system (S) provides a gaseous media at a pilot pressure level to said pressurizable chamber (12) and to said actuation line (7) in a position downstream the first actuation device (4A, 4B) or via said pressurizable chamber (12) for detection of any leakage of gas in the control and monitoring system (S), said pilot pressure gaseous media preferably being low pressure nitrogen gas. The invention further relates to a pneumatically, high pressure gas powered emergency release coupling (1) and a control and monitoring method for such a system (S).

Systems and methods for fueling (or charging) communication, for example between a hydrogen fueling station and a hydrogen powered vehicle (or an electric vehicle and charging station) may utilize near field communication as well as vehicle to infrastructure communication. Safety information, fueling or charging information, payment information, and other information may be transmitted, and the redundant nature of the communication permits fault recovery and improved process monitoring. In this manner, fueling and/or recharging is made safer, faster, and more efficient.

A fluid distribution system including an asphalt sealer vessel having an agitator, a water source and an additive vessel remotely controllable so as to permit selective distribution of fluid to a customer vessel.

A system includes a plurality of mobile fuel distribution stations. Each mobile fuel distribution station includes a mobile trailer, a pump, a manifold, a plurality of hoses, a plurality of fuel caps connected or connectable with the hoses and attachable on fuel tanks of pieces of equipment, a plurality of valves, and a plurality of fuel level sensors operable to generate signals indicative of fuel levels in the fuel tanks. The mobile fuel distribution station is configured to operate the pump responsive to a low fuel threshold to provide fuel to the manifold, from the manifold to the valves, and from the valves through the hoses. A server is operable to communicate with the mobile fuel distribution stations. An electronic device is operable to communicate with the server and display the fuel levels in real-time.

This disclosure includes safety valves, vehicles and fueling stations having the same, and related methods. Some safety valves have a valve body defining a fluidic network including an inlet and an outlet, a piston disposed within and movable relative to the valve body between a first position in which the inlet is in fluid communication with the outlet and a second position in which fluid communication between the inlet and the outlet is prevented, and a heat-defeatable barrier that prevents movement of the piston to the second position. In some safety valves, the piston is biased toward the second position. In some safety valves, the piston includes a channel disposed between first and second ends of the piston, and when the piston is in the first position, the inlet is in fluid communication with the outlet via the channel.
